Applicant's summary and conclusion
- Interpretation of results:
- other: Not sensitizing
- Conclusions:
- The allyl methacrylate (96-05-9) was considered to be not sensitizing to guinea pig
- Executive summary:
The skin sensitizing study of allyl methacrylatewas carried out inHartleyalbino guinea pig by patch test method.10 animals in treated group and 10 animals in positive control group were observed.Dinitrochlorobenzene (DNCB) used as positive control. The repeated insult patch tests carried out either with test material or with dinitrochlorobenzene (DNCB) 4 times in 10 days.No skin reactions were observed in treated group while all the animals in positive control group were sensitized. Therefore, based on the results obtained, theallyl methacrylate(96-05-9)was considered to be non-sensitizing to skin of guinea pig.
